Yeah, that’s the first time/place it was recorded (excluding the Justinian plague), although the Italian/Greek factories there were importing goods, people & animals from all over the place so it doesn’t necessarily mean Crimea was where it came from originally.

Never the less, it does make much more sense that it originated near where it was first recorded, rather than in China, then travelling half way across the world without anyone bothering to write about it or it’s uniquely awful symptoms.
